Abstract

A computer-aided design (CAD) system is developed for automatic process design and finite element (FE) modeling of axisymmetric deep drawn components. Using the theoretical and experimental rules, the system initially designs the process sequence of the component. The obtained process sequence is automatically modeled in abaqus software and the system tests whether failure occurs. The failure is supposed to happen when the fracture is predicted in FE simulation. If failure is predicted, the system changes the appropriate process parameters and carries out the simulation process again until all drawing stages are successful. The system returns the requested parameters for die design such as part geometries in middle stages, drawing forces, blank-holder forces, die, and punch profiles radii. The system is successfully tested for some components found in industry and handbooks.
